Multiplication of two custom field values.

[Prasad Nagarale]

I have 2 custom fields A and B.

Both are single select list with values 1 to 10.

how to store the multiplication of two custom field values into new custom field  i,e in c.

C = A * B.

[Chris Buzon]

I have found that you need to refer to the custom fields directly by their numerical values, not through the names of the fields (human-readable names I mean). 

Here's an example for some date fields I was manipulating:

{{issue.customfield_12527.diff(issue.customfield_12526).abs.hours}}

[Jack Brickey]

yes that is absolutely true. you can find that detail by going to the custom fields page under admin > issues > custom fields and selecting the field and inspecting the URL. That is one way but there are others, e.g. JQL.

Jira Misc Custom Fields has a calculated custom field as well.

Do I need to have the paid Jira version to be able to create Calculated Number Fields?

[Jack Brickey]

you would need an addon, e.g. Scriptrunner, Power Scripts, Automation for Jira, etc. I use A4J but I'm on cloud and it is built in there (free).

Hi @Jack Brickey can you please point me to the link where I can find the free built in A4J on cloud ? I have a similar requirement to store the multiplication of three custom field values into new custom field. I tried as shown in the screenshot but not successful so far. Thanks in advance!

[Jack Brickey]

I’m a bit confused on your request. From the screenshot it appears you have already found automation. Maybe you are looking for the documentation to assist you? If so here is a link - smart-values-math-expressions 

[Naveen Sidda]

Thanks for the response and link. I am aware of the link you provided. The screenshot is what I set myself not what I already found. I am still not able to store the multiplication of three custom field values into new custom field which is why I am reaching out to you, if you can help me find the free built in A4J on cloud for my requirement.

You get to A4J automation for a specific project here >> project settings - Automation. If you want to create a multi-project automation then navigate to here >> admin (click on cog upper right) > System > Automaton (sidebar) > Global automation
